Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval diamond, its elongated silhouette casting a subtle glow that seems to stretch across the finger. This semi-set solitaire ring foundation in warm 10K rose gold invites your choice of a 6 x 4 mm oval center stone, known for its graceful elongation that visually lengthens the hand with quiet elegance.

Crafted in our Williamsburg studio, the band’s smooth finish and delicate profile ensure a comfortable fit for daily wear. The low-set prongs cradle the stone securely while maintaining a refined, unobtrusive presence that pairs effortlessly with stacking bands or a wedding band.

Each piece reflects our commitment to ethical jewelry: the setting is designed exclusively for lab-grown diamonds, offering clarity and brilliance without compromise to sustainability.

This ring suits those who appreciate artisan craftsmanship and a subtle statement—its slender rose gold band complements slender to medium finger shapes, while the oval shape adds a touch of vintage-inspired sophistication.

Should you need resizing or prefer a different stone cut, our Brooklyn studio welcomes consultations to tailor your design with care and precision.
